Polyolefinic resin composition having superior paintability

Abstract

The present invention relates to a polyolefinic resin composition having superior paintability which comprises: (A) 40 to 80 parts by weight of a crystalline polypropylene resin; (B) 1 to 50 parts by weight of a thermoplastic olefinic rubber prepared by dynamic-crosslinking 10 to 70 parts by weight of a crystalline polypropylene resin with 90 to 30 parts by weight of an ethylene-.alpha.-olefin rubber; (C) 0.5 to 30 parts by weight of a polypropylene resin modified by grafting a polar monomer which has a physical affinity, but is not reactive, with an ethylene copolymer or ethylene copolymer rubber modified with .alpha.,.beta.-unsaturated carboxylic acid or a derivative thereof; and (D) 1 to 40 parts by weight of said modified ethylene copolymer or ethylene copolymer rubber based on 100 parts by weight of the total weight of the components (A),(B) and (C).

Dependencies are inferred from the claim text.
